Regulated Marauder - Field and Target Edition on Crosman website
- Thread starter MJS
- Start date
This web page has been up and down at Crosman for months. I think it was originally announced at Shot Show or something similar. The shelved it at one point, Crosman got sold (Yes, the whole company) and other stuff happened since announced. If they really are producing it, many will be extremely happy.
I hope, hope, hope, it's really going to happen.

They announced recently that it WILL happen but only through the custom shop. Reg will be constantly on no on and off like they first we're gonna have and then I believe we're gonna bring in LW barrels in .177 and .22. Think that's all they had as info as far as I know. Forget where I saw that.

I got an email from the new marketing manager at Crosman that he's working on getting me a release date for the new regulated Marauder. We've an upcoming phone date so perhaps I'll learn of it then. Will update this thread if I find out.

I'm impressed with the accuracy of that gun! I'm hoping the Mrods now have those barrels. Ordered a refurb .22 from AGD yesterday

Saw this too. My guess is that it isn't adjustable (at least externally) because of how easily someone could muck up their gun. I would think that they are going to make it internally adjustable, though. If for no other reason, they're offering it in multiple calibers.

This brings up another subject.... When will Crosman-Benjamin come out with a REAL regulated and/or bottled airgun? I'm not holding my breath after this latest announcement.

As for the barrel - I have a gen 2 and it appears to have the new barrels from a couple years back. Very accurate in default configuration.
As for the regulator - My understanding with the Field Target regulator, is that they changed the specs so it's always ON. No turning it off.
From the look of the video, the regulator is set somewhere between 1300 and 1400PSI, so setup for a Crosman Premier Dome or JSB Exact might work well, though heavier. I suspect the JSB Exact Heavy would fly at around 720FPS, so not have the required range. Looks to me as it's specifically setup as a field "target" gun. Nothing wrong with that, just set your expectations accordingly. If you want to adjust it to send heavier pellets or have lots and lots of adjustment range, I'd bet the regulator will limit the adjustments a bit.
I'd like to see some groups at 75 and 100 yards with the various pellets to see what it can really do. Looks like 100 yards is well within reach, but how consistent? Can it keep up with an FX Streamline or maybe even an Impact? Sort of doubt it, but it'd be fun to see. If it can keep up with the likes of a RAW and Streamline and Impact, that's be a huge price point advantage for the sport.
And even though Crosman doesn't offer a bottle gun, it looks like they got 60 shots on full power (if I counted right in the video) so no wasted air. That's very respectable from a cylinder gun. did anyone else validate the count? They lost count.

They took exactly 80 shots. The 1st 70 shots are at an ES of 27 & standard deviation of 6.2. Shot string graph below:

Might just be.
Crosman had the regulated marauder figured out in '08-'09, no worries as it if it works.

Agreed spysir, it looks like they know what their doing based on the shot string. I'm looking forward to someone getting this rifle and performing a tear down to see how she ticks. Also looking forward to seeing what others have already accomplished with the current gun in combination with the available after-market regulators, hammers & hammer springs. Crosman may have the after-market beat on price at $700. $450 for a Marauder + $125 Huma + $180 MM or LW barrel, you get the idea.

parallex,
strictly dropping a regulator in a stock gen 1 .177
http://www.airgunadvice.net/viewtopic.php?t=13340
And Jeff's blog has better "just dropped in info" and pictures showing just how simple this project is:
Marauder Project – Installing A Regulator
again a gen 1 and naturally you can get much better numbers easily but those are drop in reg for dummy numbers.

Techie stuff I really don't understand -
The artical above, Installing a Regulator set the regulator pressure at 1850PSI. It looks like the Marauder FT is set at around 1350. Field Target gets 70 shots per fill with 3000 PSI fill.
Tuning the Marauder has three components. Hammer Spring (HS) Preload, Hammer Throw (HT), and Transfer Port.(TP)
Using the HS and HT basically determine how far the valve opens and how long it's open. The Transfer Port controls the speed the air enters the chamber.
Would using a regulator mean that the HS and HT adjustments need to be enough to open the valve enough to empty the regulator and that's it? Sure would make tuning simple.
Then open the TP to max.
So, the hammer hits and opens the valve. Valve could be open for way too long on a non regulated gun and waste a lot of air but because the regulator limits the amount of air that can leave the reservoir, the HT and HS adjustments just aren't that critical to get right on the money?
As long as the air can hit the pellet fast, all is good? Is it really that simple?
Then I guess you can use the TP to fine tune the pellet speed. That simple?? or am I dreaming?

OK. I'm on a roll with questions now.
Further, is the Marauder FT specifically setup for the Crosman Premier Domes 14.3 gr pellet? What if I want to shoot the JSB Exact's or JSB Exact Heavy? Can I adjust the gun enough to shoot different weight pellets well or does the regulator severely limit my adjustment choices?
Inquiring minds want to know!
Same questions would go for installing a Huma regulator as well. One can adjust a Huma, but only after the gun is depressurized and disassembled. For all practical purposes, set it and get it right or take the gun apart.
Thoughts? Am I completely out in the deep end of the ball park?

It does seem like the extra bolt seen on the gun is strictly for turning the regulator on or off, this seems like the easiest way use that "on/off capability." Regarding the questions for tuning the gun, I think you're thinking overestimating what a regulator can do. Hammer spring tension and throw still have an effect on regulated guns and can cause air to be wasted or insufficient. For some good advice on tuning, Ted just released a video where he shows how he tunes his guns. I do think that Crosman will tune the guns for their pellets beforehand, I don't see a good reason why they wouldn't. We'll have to wait for them to be available before anything is for certain, though.

OK all sounds good, but another question. Many FT matches limit power. At 830 FPS, the Premier Dome .22 at 14.3 gr is nearly 21 Foot Pounds energy. The tuning seems a bit high for field target matches, especially in Europe. Many matches, if international flavor limit to 12 foot pounds energy. The tuning is very interesting at that point.
Maybe if Crosman would respond directly? we could ask these questions directly of them.
So much to learn about the sport!

The on/off capability is gone. That is no longer apart of the gun. It is a constant regulator now. Power is restricted in some field target. Some is 12fpe limit some 20fpe limit and others are no limits but I believe .25 Cal and up is off limits. I am not into field target at all but I believe from what I've learned those are some basics.
Tuning a regulated gun is tricky. You can't just get to whatever fps you want with hammer spring and throw alone. Really depends hugely on the reg pressure. Like Ted has mentioned when tuning a regulated gun you ant to find the max speed you can get out of that and then back it down 10-15fps. You tend to get the best consistency at those settings. If you aren't getting the power you want then you need to adjust the reg pressure for the best results.
